The OnePlus Ace 5 is experiencing an issue where a reboot command initiated through KernelSU results in an endless loop. Users report that the device lockscreen appears to be waiting for a reboot, and upon unlocking, the phone immediately restarts again. This behavior occurs despite attempting to access Safe Mode via repeated volume down presses during startup.

Before the KernelSU-initiated reboot loop starts, the following sequence appears in the system logs:

* Logs indicate trouble finding sensitive file keys.
* The Device attempts to prepare the data partition for user access.
* The system mounts the emulated filesystem for user data.
* When unmounting these partitions and preparing the phone for shutdown, a Binder transaction error occurs with code BR_29189.

After the loop starts, attempts at entering Safe Mode are unsuccessful as KernelSU doesn't enforce it, contradicting the usual behavior. Interestingly, modules updated normally during this loop, but the user is perpetually stuck in the reboot cycle.

As the log indicates 'Invalid argument' errors, the issue might stem from corrupted system files or drivers. Further investigation into those logs will provide more details about the specific error source.

Here's what you can try to troubleshoot this issue:

* **Repair your system:** Try repairing the system using the built-in Android repair tools available on your device.

* **Perform a factory reset:** This should be considered a last resort, as it will erase all your data. Make sure to back up your data before proceeding.
* **Check for software updates:** Ensure you're running the latest version of OxygenOS and KernelSU.
* **Contact OnePlus support:** If none of the above solutions work, reach out to OnePlus support for further assistance.
